FoFiX

FoFiX is a Frets
on Fire fork with plenty of features, customizable themes and
options. The aim of the game is to play guitar with the keyboard or
instrument controllers as accurately as possible.

FoFiX tries to resemble Guitar Hero and Rock Band to a greater
extent than most other modifications while still maintaining some of
Frets on Fire' original aspects. Play guitar, bass or drums
along with your favorite songs on your computer using either your
keyboard or instruments. You can use your Guitar Hero or Rock Band
instrument controllers.

Separated audio tracks will mute when you fail to hit or
sustain the required notes correctly to simulate a real concert-playing
experience.
